Abstract：The corrosion of materials brings serious economic and safety problems to the society. Superhydrophobic coatings have great potential for anti-corrosion due to the special structure of the surface. In this paper, the establishment and development of several superhydrophobic theoretical models were reviewed. The theoretical basis and existing problems of applying superhydrophobic coatings to corrosion protection were analyzed. Several methods, such as hydrothermal method, sol-gel method and etching method, were discussed. The commonly used superhydrophobic coating preparation methods were summarized. In the field of large-scale application and corrosion protection of superhydrophobic coating, it is necessary to study the corrosion protection behavior of the coating in theory, simplify the process, reduce the cost,and improve the mechanical stability of the coating and the controllable transformation of water drop on the surface of the coating.
